You can never have enough...

My fish don't like chlorinated water, neither does my cat, so I fill a watering can, leave it for a few days, then use it for the critters. For me I just add tea bags, or coffee sachets, or citrus juice at the monent, because there's plenty of that available since I started feeding the trees...

As for the heat pump water heater, there are a few on the market to investigate. Outside wouldn't be an issue, but installation costs might well be. We shall see.

The water straight out of the tap tastes really bad, need to leave it in a jug in the open air for a few hours to let the chlorine disburse.

Bluuuurk!   Far prefer our roof water with added natural enrichments
